I would like to write a proxy compatible with windows 98/XP.
I have looked at the articles here on CP and the two relevent articles don't apply to my particular problem I don't think.
For instance, the firewall example here on CP uses features specific to XP (I think). I want to write a firewall, but need it to work in win 98 also. Does anyone know of articles which might explain the different approaches used in writting a http proxy? basically I just want to capture HTML before being sent to browser, preferably both IE and Netscape. I have already considered using IWebBrowser2 to accomplish what I want to do also.
Edit Actually I really need to capture HTTP and HTML...so maybe IWebBrowser2 wouldn't work at all 
Thanks

I want to design a windows program that can communicate using the serial port. I bought C#.net standard not knowing it did not have serial communcations framework and the work around is using MSComm.ocx from Visual Studio 6 which i do not have. Does C++.net standard have serial port communications framework? Or would buying Visual Studio.net solve my issue?
Thanks,
karl

For serial communication over COM port you have to use API functions like
CreateFile, WriteFile, ReadFile etc.
or alternatively you can use an OCX component, like MSComm.ocx.
Both ways can be achieved from C#, too.

Does any one know a fairly easy way to set the focus to a given edit control in a dialog box? Thx,
Ralf.

I also do myEdit.SetSel (0, -1); before setting focus to an edit control after displaying a validation error message. This prepares the control for overwriting.

I need to send data out in two short ints in a message. The source data is in floating representation, range -180.00 to +180.00. This needs to be converted into a scaled 32 bit 2's Complement integer value
So what I need to do is normalise the data;
i.e. float f = 99.9;
f = f/180; // 0.555
Now I need to extract the bits that reprsent the .555 and convert them to a 32 bit bit 2's Complement integer
I was planning to use the union as follows:
union
{
int intValue;
unsigned short buff[2];
}convert;
So once I have converted the float to int I can assign the buff[]
e.g. convert.intValue = floatToInt(f/180);
So now I can load the message using convert.buff[0] and convert.buff[1]
Note I need to check the conversion, so I am planning to do the following:
float f_out = (float) ((buf[0] << 16 | buf[1])*180);
Question how to I convert the float to int?

int i = int ((f/180.0f)*float(MAX_INT));
I don't remember exactly what MAX_INT is called. But it is in limits.h.
float f = float (i) / float (MAX_INT) * 180.0f;

Hi everyone,
I am writing a win32 service that listens on a socket. When I run the application in a normal console window, it works fine. However, I cannot initialize the socket when I run it as a service. I found out that the following line was needed:
AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0);
However, this line does not work when I run the service. Coz I guess there is no WinAPP object. But the CSocket object does not initialize and the sevice dies.
Anyone has any ideas how I can init MFC sockets in a service. This is really urgent. I would really appreciate any help.
Thanks,
Pankaj

For an easy way out, first read Xiangyang Liu's article Start Your Windows Programs From An NT Service[^]
This article presents you with a service, which is able to start programs before users log on and keep them running after users log off. This way, you don't need to ponder about how to implement MFC to a Win32 service. You can just write a full-fledged MFC application using the MFC App Wizard, and let the XYNTService worry about the rest.

Yeah,
I think I will go for that solution. Thank you so much for pointing that out to me.

Recently i did a packet capture on my network of what was being sent when i logged into my router and viewed the status page that has the current ip for my router (the ip for the internet side). To my surprise i saw a packet of the http connection that had some XML data in it, like the external ip-address for one. But then when i pressed refresh in IE, or i closed and relogged into my router it didnt send that XML data anymore. Now my question would be why is this? And is there any way i can surely get this XML reply from my router when i connect to it manually? (I don't know much about XML)
Thank you for any assistance.

I desperately need help on setting up and using the FlatSB with C, no MFC.
I, by all means know nothing about C++ (btw, sorry if i posted this here), and I just migrated from VB.
I found some samples, like JonathanLivingstone's sample (http://www.codeproject.com/dialog/ScrollableChildDialog/ScrollableChildDialog_demo.zip) which is exactly i wanted.
I need to scroll (with FlatSB) my dialog which has about 50 editboxes & labels.
I know how to do this with VB. I just need to use canvas to group all of these controls, and then scroll it.
But I don't know how to do these with win32 API & C.
Please help me! 
I really appreciate any help regarding this.

In my program I have 2 file:input and output.
When I open the first file I am reading the lines where
I have my specific string, other lines I am skiping.
In my output file I need to write my lines with tab delimeter.
How do I do this?

What are you using to read with: FILE*, istream, CFile, etc?
Five birds are sitting on a fence.
Three of them decide to fly off.
How many are left?

Then use ostream::write() to write the data to an output stream (e.g., file).

hello all,
my name is durval and i've the following problem in my project:
when the color-palette from the windows-desktop (properties)
16-bit (65536) is set. on ms-c++ print-preview (mfc) the
::StretchBlt(...)/::StretchDIBits(...)/::::BitBlt(...)
doesn't work properly. the bitmap is dividing in 2 parts, the
right (1/3 from the bitmap) will be put on the left place and
the left is displaced to the right.
at all the other color-settings there's no problem: 8-bit, 24-bit...
do you know this problem?
please, if everybody could help me, it would be very nice.
thanx a lot,
durval.
the code:
BOOL CDib::Draw(CDC* pDC, CPoint origin, CSize size)
{
if(m_lpBMIH == NULL) return FALSE;
if(m_hPalette != NULL)
::SelectPalette(pDC->GetSafeHdc(), m_hPalette, TRUE);
pDC->SetStretchBltMode(COLORONCOLOR);
// ::BitBlt( pDC->GetSafeHdc(), origin.x, origin.y, m_lpBMIH->biWidth, m_lpBMIH->biHeight, memDC.m_hDC, 0, 0, SRCCOPY );
// ::StretchBlt( pDC->GetSafeHdc(), origin.x, origin.y, size.cx, size.cy, memDC.m_hDC, 0, 0, m_lpBMIH->biWidth, m_lpBMIH->biHeight , SRCCOPY );
::StretchDIBits(pDC->GetSafeHdc(), origin.x, origin.y, size.cx, size.cy,
0, 0, m_lpBMIH->biWidth, m_lpBMIH->biHeight,
m_lpImage, (LPBITMAPINFO) m_lpBMIH, DIB_RGB_COLORS, SRCCOPY);
return TRUE;

Hi Guys,
I'm having a heck of a time doing some rounding here, hoping someone has a quick solution.
Example:
CHAR string[xx] = "1.019", null terminated string holding the current release.
FLOAT instver, intended to hold the float value of string ( I want it to be 1.019 )
When I do:
sscanf ( string, "%5lf", &instver );
My result is always: 1.0189999
I've tried:
instver = atof ( string );
And I still get the same results. I've done some peeking around the helpfile, can't find anything that will let me truncate/round the decimal spots.
Anybody?
Thx.
Mike.

You are always going to get this degradation of floating point accuracy. You need to read up on how floats are stored in IEEE 754 specification.
Floats are stored as a binary value that is composed of the mantissa and the exponent just like in regular scientific notation, however they are binary, so you are converting a decimal format into binary - this is going to cause round-off error.
It is still basicly fairly accurate. If it is just a cosmetic thing you can use format statements and they will round to the correct value for you. printf("%.3f", val); will do this.
